FIG. 1 illustrates a schematic plan view of an array substrate 100 according to some embodiments of the present disclosure, while FIG. 2 illustrates a schematic structural view of the array substrate according to some embodiments of the present disclosure as attached to respective exemplary first and second common voltage terminals 171 and 172.

Meanwhile, FIG. 4 illustrates a cross-sectional view of the array substrate according to some embodiments of the present disclosure, the cross-sectional view of FIG. 4 illustrating a cross-sectional view along the A-A′ line shown in FIG. 2.

As shown in FIGS. 1 and 4, the array substrate 100 includes a base substrate 110, one or more first common voltage lines 115, and one or more second common voltage lines 116 arranged in an alternating fashion along a common edge and extending laterally through the array substrate 100. The array substrate 100 can then also include one or more gate lines 124 provided between the first and second common voltage lines, the one or more gate lines also extending laterally through the array substrate 100, of the array substrate 100 can then be provided with one or more data lines 123 provided along an alternative edge, the alternative edge being perpendicular to the common edge. such that the data lines 123 extend through the array substrate 100 substantially perpendicular to the first and second voltage lines 115 and 116 respectively.

The data lines 123 and the first and second voltage lines 115 and 116 respectively and gate lines 124 then forming a grid having cells containing a plurality of display sub-pixels 111 therebetween. In other words, as illustrated herein the plurality of display sub-pixels 111 correspond to the regions defined by the plurality of gate lines 124 and the plurality of data lines 123 crossing each other, the plurality of display sub-pixels 111 are arranged in the form of an array.

Each display sub-pixel 111 can then be provided having a pixel electrode 112 having the left side 112 a and the right side 112 b of a pixel electrode 112 are marked differently in FIG. 1, the left side 112 a being marked by lattice and the right side 112 b being marked by blank) it is only for the purpose of clear illustration, the left side 112 a and the right side 112 b of any particular pixel electrode 112 can be connected to each other, for example, the overall shape can be provided as a block. In other words, each sub-pixel 111 is bifurcated into two opposing regions corresponding to a left side 112 a and a right side 112 b.

As shown in FIG. 1, the data lines 123 extend in a first direction D1, the gate lines 124 extend in a second direction D2, the first direction D1 and the second direction D2 cross each other, for example, perpendicular to each other. However, it will be appreciated that in some more complex embodiments, the array can be formed having more than 4 edges, such as hexagonal or octagonal patters so as to form more complex grid formations.

As illustrated herein, three adjacent display sub-pixels 111 in the first direction D1 can be grouped together so as to form a display pixel 119. The first common voltage lines 115 and the second common voltage lines 116 can then extended in parallel in the second direction D2, wherein the orthographic projections of the first common voltage lines 115 and the second common voltage lines 116 on the base substrate 110 can then be spaced from each other and arranged alternately in the first direction D1.

It should be noted that, the extension of the gate lines 124, the first common voltage lines 115 and the second common voltage lines 116 in the second direction D2 only refers to the extending direction of the gate lines 124, wherein the first common voltage lines 115 and the second common voltage lines 116, does not refer to the gate lines 124, the first common voltage lines 115 and the second common voltage lines 116 themselves are in the form of straight lines that are parallel to the second direction D2.

In other words, according to practical needs, the gate lines 124, the first common voltage lines 115 and the second common voltage lines 116 can be in the form of straight lines that are parallel to the second direction D2, but they can also be polygonal lines that are not completely parallel to the second direction D2 but only extend generally in such a direction.

Similarly, although the data lines 123 in the figure are illustrated herein as straight lines extending in the first direction D1, there are no limitations herein implied thereby, for example, the data lines 123 can also be polygonal lines extending generally in the first direction D1. Such polygonal lines could then be utilized to form sub-pixels 111 having any desired shape or characteristic.

In contrast to FIG. 1, the array substrate 100A as illustrated in FIG. 2, can be arranged such that each display sub-pixel 111 can further be provided with a first common electrode 113 and a second common electrode 114, wherein the first common electrodes 113 are connected to a first common voltage line 115, while the second common electrodes 114 can then be connected to a second common voltage line 116.

As shown in FIG. 2, the first common electrodes 113 and the second common electrodes 114 can be arranged side by side over or on the array substrate 100, wherein the first and second common electrodes can then be electrically insulated from each other so as to prevent electrical interference therebetween. In other words, they can be arranged side by side on a plane defined by a surface of the array substrate 100, therefore first and second common electrodes 113 and 114 are respectively located along different portions of each of the display sub-pixels 111.

For example, the orthographic projections of the first common electrodes 113 and the orthographic projections of the second common electrodes 114 are arranged such that they are spaced from each other and arranged alternately in the second direction D2. In this manner, the first common electrode 113 can be associated with a left side 112 a of each sub-pixel 111 while the second common electrode 114 can be associated with a right side 112 b of each sub-pixel 112 b.

As shown in FIG. 4, the first common electrodes 113 and the second common electrodes 114 can be located at a common depth or layer, as a result, the manufacturing process can be simplified. However, in some embodiments, according to practical needs, the first common electrodes 113 and the second common electrodes 114 can also be configured at different depths or layers.

As shown in FIG. 4, in a particular display sub-pixel 111 of the array substrate 100, the pixel electrodes 112 can be configured such that they are covered about an upper surface by both the first common electrodes 113 and the second common electrodes 114, i.e. in a direction that is perpendicular to the base substrate 110, as a result, when a pixel voltage is applied to the pixel electrodes 112 during display operations, the pixel electrodes 112 respectively interact with the first common electrodes 113 and the second common electrodes 114, therefore, display operations are conducted differently between respective right or left s portions of each of the display sub-pixels 111.

It should be noted, when providing the first common electrodes 113 and the second common electrodes 114 at the same depth or layer, the first common electrodes 113 and the second common electrodes 114 can be provided of a common material through the same patterning process. For example, the first common electrodes 113 and the second common electrodes 114 can be formed from a single conductive layer through a single patterning process.

In some such embodiments, the first common electrodes 113 and the second common electrodes 114 can be formed from a single mask through a single photolithography process. For example, the first common electrodes 113 and the second common electrodes 114 can be provided having a common plane; In some such embodiments, the first common electrodes 113 and the second common electrodes 114 can be provided at different planes or depths but belong to the same structural layer.

As shown in FIG. 2, the first common electrodes 113 and the second common electrodes 114 can be configured to be connected to different common voltage terminals of the driving circuit to receive a first common voltage and a second common voltage. For example, as shown in FIG. 2, the first common electrodes 113 can be connected to the first common voltage terminal 171 of the driving circuit through the first common voltage line 115 to receive the first common voltage outputted by the first common voltage terminal 171, the second common electrodes 114 can then similarly be connected to the second common voltage terminal 172 through the second common voltage line 116 to receive the second common voltage outputted by the second common voltage terminal 172.

In some embodiments, the first common electrodes 113, can be provided at one side of the array substrate, for example, the upper side or the lower side, which can also be directly connected to the first common voltage terminal 171. Similarly, the second common electrode 114, can be provided at one side of the array substrate, for example, the upper side or the lower side, which can then similarly be directly connected to the second common voltage terminal 172.

In some embodiments, the driving circuit is connected to a control device (not shown in the figures) and output having common voltages needed at different common voltage terminals according to the control signals received from the control device. The control device outputs corresponding control signals according to display modes, i.e. 2D or 3D display mode.

In some embodiments, the value of the first common voltage and the value of the second common voltage can be different, as a result, each display sub-pixel 111 can be configured to provide at least two different gray scales. For example, as shown in FIG. 2 and FIG. 7, FIG. 7 being related to the display device and will be described in detail later, during display operations, the region of the display sub-pixel 111 corresponding to the first common electrode 113, for example, the region at the left side of the display sub-pixel 111 as marked by lattice in FIG. 1, can be employed so as to provide an output from this particular image pixel relating to a first image 155, for example, the left eye image, the region of the display sub-pixel 111 corresponding to the second common electrode 114, for example, the region at the right side of the display sub-pixel 111 that is marked in white color, can be employed to provide an output from this particular image pixel relating to a second image 156, for example, right eye image.

For example, as shown in FIG. 2 and FIG. 7, when the first image 155 and the second image 156 respectively reach a left eye and a right eye of a user, the user can have stereo perception, that is, the user can see an image 157 that has 3D visual effect, as a result, the display device that includes the array substrate 100 according to embodiments of the present disclosure can achieve 3D display function without reducing resolution.

In some embodiments, the value of the first common voltage and the value of the second common voltage can also be the same, as a result, each display sub-pixel 111 can be configured to provide the same gray scale. In this case, the array substrate 100 according to some embodiments of the present disclosure can be employed to achieve 2D display function.

Compared with the display device 10 of FIG. 12, the display devices including the array substrates 100 according to embodiments of the present disclosure can realize 2D display function without reducing resolution. For the purpose of clear illustration, the principles of realizing 2D display function without reducing resolution will be described in detail in the embodiment of display device 10, it will not be repeated herein.

In some embodiments, as shown in FIG. 2, the first common electrodes 113 of at least two adjacent display sub-pixels 111 can be electrically connected, wherein the second common electrodes 114 of at least two adjacent display sub-pixels 111 can then be electrically connected, as a result, the number of common voltage lines of the array substrate 100 can be reduced, therefore, the aperture ratio of the array substrate 100 can thus be improved and the cost of the driving circuit, which for example, can be provided as an integrated circuit, can thereby be reduced as it would require reduced complexity.

In some embodiments, as shown in FIG. 2, the first common electrodes 113 of at least two adjacent display sub-pixels 111 in the first direction D1 can then belong to a first common block electrode; in some such embodiments, the second common electrodes 114 of at least two adjacent display sub-pixels 111 in the first direction D1 can thus belong to the first common block electrode.

In these embodiments, due to the first common electrodes 113 of at least two adjacent display sub-pixels 111 in the first direction D1 being electrically connected without additional connection lines and the second common electrodes 114 of at least two adjacent display sub-pixels 111 in the first direction D1 can be electrically connected without additional connection lines. By doing this, the number of common voltage lines can be reduced without increasing the complexity of the process.

In some embodiments, the first common electrodes 113 and the second common electrodes 114 can be formed at a common layer at a similar depth over the base substrate 110. In such an embodiment, the first common voltage lines 115 and the second common voltage lines 116 can then be formed at the same layer, wherein one or more intermediate insulating layers can be placed between the layer where the common electrodes are located and the layer where the common voltage lines are located.

For example, as shown in FIG. 1 and FIG. 2, the first common electrodes 113 of at least two adjacent display sub-pixels 111, which extend in the second direction D2, can be electrically connected to the same first common voltage line 115, i.e. a single first common voltage line 115, through the first via a connector 117 which extends through the intermediate insulating layer. Then, the second common electrodes 114 of at least two adjacent display sub-pixels 111 which extend in the second direction D2 can then be electrically connected to the same second common voltage line 116, a single second common voltage line 116, through the second via an alternative connector 118 which extends through the corresponding intermediate insulating layer.

In this manner, the first common electrodes 113 of at least two adjacent display sub-pixels 111 in the second direction D2 can be electrically connected and the second common electrodes 114 of at least two adjacent display sub-pixels 111 in the second direction D2 can be electrically connected without configuring additional connection lines, as such, the number of common voltage lines can be decreased without increasing complexity of the process.

FIG. 3A illustrates a schematic plan view of another array substrate 100 provided by embodiments of the present disclosure, FIG. 3B is an enlarged view of the D region of the array substrate 100 of FIG. 3A.

As shown in FIG. 3A and FIG. 3B, the first common electrodes 113 of adjacent display sub-pixels 111 in the first direction D1 can be configured such that they belong to a common block electrode, wherein the second common electrodes 114 of the illustrated on an opposing side of each adjacent display sub-pixels 111 as extending in the first direction D1 can similarly belong to an alternative common block electrode.

Additionally, the first common electrodes 113 of each adjacent display sub-pixels 111 in the second direction D2 can then each be connected to the same first common voltage line 115, and, the second common electrodes 114 of the each adjacent display sub-pixels 111 in the second direction D2 can then similarly each be all connected to the same second common voltage line 116.

It will be appreciated that the number of adjacent display sub-pixels 111 first common electrodes 113, and second common electrodes 113 within the matrix or array can be expanded or reduced or otherwise adjusted to meet a particular need. For example, in order to further reduce the number of common voltage lines, at the number of adjacent display sub-pixels 111 can then be configured as a larger value. For example, in order to improve the gray scale control precision of the display sub-pixels 111, at least one of M and N can be configured to be a smaller value.

It should be noted, the schematic plan view of the first common electrodes 113 and the second common electrodes 114 as shown in FIG. 2 is provided only for exemplary purposes, and that based on practical needs, the shapes of the first common electrodes 113 and the second common electrodes 114 can also be rectangular or any other suitable polygonal shape.

For example, in the cross-sectional view of FIG. 4, for each sub-pixel 111, the orthographic projection, that is, the shape of the cross-section in the cross-sectional view, of the first common electrode 113 and the second common electrode 114 over the projection plane, that is, the surface of the paper, is roughly in a first concave shape, for example, a first V shape, the orthographic projection of the pixel electrode 112 over the projection plane is roughly in a second concave shape, the first concave shape and the second concave shape, for example, a second corresponding V shape, which correspond to each other in the direction that is perpendicular to the base substrate 110.

As a result, optical distortion of the display device 10 including the array substrate 100 will be reduced. For example, the shapes of the first concave shape and the second concave shape are roughly the same or similar, due to the fact that they nest within each other. As a result, the first concave shape and the second concave shape have corresponding portions that are “parallel” to each other, therefore, the distances between the common electrodes and the pixel electrode are substantially uniform, which, as a result, can operate so as to further reduce optical distortion.

In some embodiments, the orthographic projection of a pixel electrode 112 over the base substrate respectively can be configured such that it overlaps with the orthographic projection of a first common electrode 113 and the orthographic projection of a second common electrode 114 over the base substrate.

In this manner, the orthographic projection of the first concave shape over the base substrate and the orthographic projection of the second concave shape over the base substrate completely overlap one another. In some such embodiments, the first concave shape and the second concave shape can be made from the same mask. For the purpose of clear illustration, the principle of reducing optical distortion will be described in the paragraphs related to the display device, it will not be repeated herein.

As shown in FIG. 2, the projection plane marked by the section line A-A′ is perpendicular to the extending direction of the first common electrodes 113, for example, it can extend orthogonally from of the plane defined by D1 and D2 as shown in FIG. 3A, or in the direction of D3 as shown in FIG. 4. In some embodiments, the size of each of the first common electrodes 113 provided which extend in the direction of the first common electrodes 113 can be larger than the sizes of each the first common electrodes 113 provided in the direction perpendicular to the extending direction of the first common electrodes 113.

In some embodiments, as shown in FIG. 4, the array substrate further includes a first insulating layer 121 and a second insulating layer 122, the first insulating layer 121, the pixel electrodes 112, the second insulating layer 122 and the common electrodes, that is, the first common electrodes 113 and the second common electrodes 114, are configured successively over the base substrate 110. In the embodiment of the present disclosure, and as shown in FIG. 4, the pixel electrodes 112 and the data lines 123 are positioned generally at the same layer.

It should be noted, the positional relationship of the first insulating layer 121, the pixel electrodes 112, the second insulating layer 122 and the common electrodes is only an example, there are no limitations herein. For example, according to practical needs, the common electrodes 113 and 114 can also be positioned between the pixel electrodes 112 and the base substrate 110. In other words, in relation to the base substrate 110, the pixel electrodes 112 can be positioned at the top and the common electrodes 113 and 114 could instead be provided directly on the substrate under the pixel electrodes.

In some embodiments, the common voltage lines, i.e. the first common voltage lines 115 and the second common voltage lines 116, and the gate lines 124 can be positioned within a common layer; in this case, the common voltage lines and the gate lines 124 can then be formed in the same alternating formation or pattern using a common process. In some embodiments, the common voltage lines and the gate lines 124 can also be provided at different layers and an insulating layer can then be provided between the common voltage lines and the gate lines 124. In some such embodiments, the common voltage lines and the gate lines 124 can be formed respectively in different patterning process, for example, different conductive layers are patterned.

In some such embodiments, a process can be utilized in which the common voltage lines can be formed by means of patterning the transparent conductive layer, forming the gates line 124 through patterning the metal layer. In some such cases, the need to employ a black matrix 221 to block the common voltage lines can be eliminated. In this manner, the aperture ratio of the array substrate 100 can therefore be improved. For example, the common voltage lines and the gate lines 124 can be located at the side of the common electrodes that is close to the base substrate 110; for example, the common voltage lines and the gate lines 124 can also be located at the side of the common electrodes that is far away from the base substrate 110.

In some embodiments, as shown in FIG. 4, the surface of the first insulating layer 121 can include a plurality of concave portions corresponding to the plurality of display sub-pixels 111. For example, as shown in FIG. 4, the orthographic projections of the concave portions 1211 of the first insulating layer over the base substrate 110 can be completely located inside a region defined by the orthographic projections of the display sub-pixels 111 over the base substrate 110.

As shown in FIG. 4, the thickness of the first insulating layer 121 at the side where the first common electrodes 113 and the second common electrodes 114 facing each other is larger than its thickness at the side where the first common electrodes 113 and the second common electrodes 114 are adjacent to each other.

In other words, the thickness of the first insulating layer 121 corresponding to the centers of the display sub-pixels 111 is smaller than the thickness of the first insulating layer 121 corresponding to the edges of the display sub-pixels 111 such that it varies with respect to the variations caused by the concave portion of the pixel electrode 112 supported thereby extending thereinto with respect to the base substrate 110.

As shown in FIG. 4, the pixel electrodes 112 can then be located inside the concave portions 1211 of the first insulating layer. Because the pixel electrodes 112 are formed over the surface of the concave portions 1211 of the first insulating layer, the cross-sectional shape of each pixel electrode 112 can also be described as having roughly a concave shape, for example, a second concave shape.

As shown in FIG. 4, the surface of the second insulating layer 122 includes a plurality of concave portions 1221 corresponding to the plurality of display sub-pixels 111 and the plurality of concave portions 1211 of the first insulating layer 121, the orthographic projection of each concave portion 1221 of the second insulating layer 122 over the base substrate 110 is at least partially overlapped with the orthographic projection of a corresponding concave portion 1211 of the first insulating layer 121 over the base substrate 110. In some such embodiments, the orthographic projection regions of the each concave portion 1221 and the and 1211 of the corresponding insulating layers can be completely overlapped.

As shown in FIG. 4, for each sub-pixel 111, at least a portion of the first common electrode 113 and a portion of the second common electrode 114 are formed inside the corresponding concave portion 1221 of the second insulating layer, as a result, the sectional shape of the first common electrode 113 and second common electrode 114 in the cross-sectional view is also formed having a concave shape, which can then be referred to as a first concave shape. In this embodiment, the first common electrode 113 and the second common electrode 114 are then formed such that they tilt towards the base substrate 110 from the side where they face each other to the side where they are adjacent to each other.

As shown in FIG. 4, the base substrate 110 is roughly in the shape of a plate, however, there are no limitations herein. For example, in some embodiments, the surface of the side of the base substrate 110 that is close to the common electrodes can also include concave portions. In this case, the concave portions 1211 of the first insulating layer can be formed without a separate patterning process for the first insulating layer 121 as the base substrate will support the insulating layer and impart concave portions thereto.

In some embodiments, each display sub-pixel 111 can include a first common electrode 113 and a second common electrode 114 which can be insulated from each other. As a result, the display devices including the array substrate 100 according to embodiments of the present disclosure can realize more than one display function, i.e., 3D display function as opposed to a 2D display function, without reducing resolution in the switch therebetween. It should be noted, the array substrate 100 according to embodiments of the present disclosure can be employed to form a liquid crystal display panel or self-luminous display panel. Some examples thereof being organic light-emitting display panels. When the array substrate 100 is implemented as a self-luminous display panel, the display sub-pixel 111 can further includes a light-emitting layer.

In some such embodiments, the region of the light-emitting layer corresponding to the first common electrode and the region of the light-emitting layer corresponding to the second common electrode can be electrically insulated from each other, for example, arranged spaced from each other, or alternatively they can be electrically connected to one another.

According to some embodiments of the present disclosure, a first common electrode and second common electrode can be a plate electrode or a slit electrode. For example, a comb electrode for the slit electrode. Further, the pixel electrode can also be provided as a plate electrode or a slit electrode.

Although according to the embodiment shown in FIG. 4, the pixel electrodes and the common electrodes, i.e. the first common electrode and the second common electrode, are located at different layers, according to some other embodiments of the present disclosure, the positional relationship between the pixel electrodes and the common electrodes are not limited to the aforementioned position relationship shown in FIG. 4. There are no limitations with regard to this positioning so long as the pixel electrode of each subpixel interacts respectively with the first common electrode and the second common electrode in the same sub-pixel when conducting display operations.

For example, the pixel electrodes and the common electrodes can also be located at the same layer so as to form an in-plane switching (IPS) array substrate. In some such embodiments, the pixel electrodes and the common electrodes can both be provided as comb electrodes, wherein the teeth portions of the pixel electrodes and the teeth portions of the common electrodes can be placed in a staggered formation.

According to these embodiments, the orthographic projection of the pixel electrode of each subpixel over the base substrate can be provided as a side-by-side arrangement with the orthographic projections of the first common electrode and the second common electrode of the same subpixel over the base substrate.

In addition, according to this embodiment, the overall shape of the electrode portions of the pixel electrode and the common electrodes can be provided having a concave shape. For example, the portion of the pixel electrode and the first common electrode that are arranged staggered and side-by-side can be located at one side of the concave shape, whereas the portion of the pixel electrode and the second common electrode that are arranged staggered and side-by-side can instead be located at another or opposing side of the concave shape, wherein the two sides face one another.

In another aspect, a display substrate is provided, the display substrate can be used together with the array substrate of the aforementioned embodiments. The display substrate includes a first substrate, the first substrate includes concave portions corresponding to the display sub-pixels provided above the array substrate, wherein a lens can then also be provided in each of the concave portions. In some such embodiments, the lens can be provided as a micro-lens.

In the following, with reference to FIG. 5A and FIG. 5B, a display substrate 200 can be provided in accordance with various embodiments of the present invention and will be described in detail below. As shown in the cross-sectional view of FIG. 5A, the display substrate 200 includes a first substrate and a lens layer. The first substrate includes a base substrate 210 and a color film layer 220 configured successively, therefore, this display substrate is a color film substrate.

The color film layer 220 includes a plurality of color filter portions 222 and a plurality of black matrixes 221 configured in the spaces among the plurality of adjacent color filter portions 222, the orthographic projection of each black matrix 221 over the projection plane, that is, the cross-section that is parallel to the second direction D2 and the third direction D3, can be in the shape of an inverse ladder. The third direction D3 and the second direction D2 can be arranged such that they intersect one another, for example, they can be arranged perpendicular to each other, or at varying alternative angles as appropriate.

As shown in FIG. 6, the color filter portions 222 and the display sub-pixels of the array substrate 100 can be arranged corresponding to one another. For example, after the display substrate 200 and the array substrate 100 are combined, the orthographic projections of the color filter portions 222 can be placed such that the base substrate 210 is located inside of the concave portions of each of the display sub-pixels 111. In some such embodiments the base substrate 210 can be formed so as to have a cross-sectional shape corresponding to an upper surface of each display sub-pixel 111.

As shown herein, the surface of each color filter portion 222 which faces away or in an opposing direction from the base substrate 210 can also include a concave portion. In some embodiments, adjacent color filter portions 222 in the first direction D1 can be provided having alternating or various patterns of varying colors, However, in some embodiments, each of the adjacent color filter portions 222 in one or more matrix rows can as the row extends in the second direction D2 can be provided having a common or similar color.

As shown in FIG. 5A, the lens layer can include a plurality of microlenses 230 arranged in the form of an array, the plurality of microlenses 230 which can be arranged on an interior surface of each of the concave portions 2411 of corresponding color filter portions 222. In some embodiments these microlenses 230 can be bonded to the color filter portions 222.

As illustrated herein, the surfaces of the microlenses 230 which are in contact with the color filter portions 222 can be provided such that they are parallel with the surfaces of the concave portions 2411 of the color filter portions 222 corresponding to the microlens 230. As a result, this arrangement allows for a situation in which no gaps exist between the microlenses 230 and the color filter portions 222.

As illustrated herein, including concave portions to the surfaces of the color filter portions 222, not only eliminates the need for a separate fixation process of the microlenses 230, but also the microlenses 230 can be more securely placed within the display substrate 200. As a result, the manufacturing process is simplified and the display robustness of the display substrate 200 is improved. For example, a plurality of microlenses 230 correspond to a plurality of color filter portions 222 can be provided in a one-to-one ratio.

As shown in FIG. 5B, the sectional shape of a microlens 230 in the cross-sectional view is illustrated herein having a diamond shape, the angle of the diamond, i.e. the acute angle, is θ, while the thickness of the microlens 230 in the third direction D3 is h.

It should be noted, the cross-sectional shape of the microlens 230 is not limited to a diamond, according to practical needs, the cross-sectional shape of the microlens 230 can also be an oval, a semi ellipse, or any other suitable shape.

When the shapes of the microlenses 230 are changed, the shapes of the concave portions of the display substrate 200 can be changed accordingly, so that the shapes of the concave portions of the display substrate will match the shapes of the microlenses 230 and the microlenses 230 can be affixed in a stable manner in the display substrate 200. As a result, optical distortion and image deterioration caused by the movement or gaps of the microlenses with respect t to the display substrate can be reduced.

For example, when the display substrate 200 and the array substrate 100 are used together, concave portions that match the concave portions of the display substrate 200 can be positioned within the display sub-pixels of the array substrate 100, as a result, optical distortion can be further reduced and image quality can be improved.

For example, when the section shapes of the microlenses 230 are ovals or semi-ellipses, the corresponding cross-sectional shapes of the concave portions of the display substrate 200 can also be provided as semi-ellipses. Further, when the array substrate 100 is used together with the display substrate 200 can also include concave portions. The concave portions of the array substrate 100 can also be adjusted according to the shapes of the microlenses 230, such that the shapes of the concave portions of the array substrate 100 correspond with the shapes of the microlenses 230.

It should be noted, the microlenses 230 are not limited to being positioned inside the concave portions of the color filter portions 222. For example, in various alternative embodiments, the base substrate 210 can include concave portions, the microlenses 230 can then be placed on an inside of the concave portions of the base substrate 210, wherein the color filter portions 222 can then be placed along or about a side of the microlenses 230.

In some such embodiments the side on which the color filter portions are placed can be an exterior or opposing side of each particular microlens 230 which is opposite from the base substrate 210. In this particular embodiment, there is no need to provide a separate planarization layer for the microlenses 230 at the side of the microlenses 230 that is opposite from the base substrate 210, therefore the manufacturing process can be simplified and the thickness of the display substrate 200 can be reduced.

For example, according to practical needs, the display substrate 200 can further include a dielectric layer, and the dielectric layer can include concave portions corresponding to the display sub-pixels 111 of the array substrate 100. In such an instance, the microlenses 230 can be provided about an inside of the concave portions of the dielectric layer, as a result, the design flexibility of the display substrate 200 can be improved.

In some instances, when the display substrate 200 includes the color film layer 220 and the dielectric layer, the dielectric layer can be provided about a side portion of the color film layer 200 that is far away from the base substrate 210. Alternatively, as illustrated in FIG. 5A, when the dielectric layer is implemented as the color film layer 220, the structure of the display substrate 200 can be including the dielectric layer.

In another aspect of the present invention, a display device can also be provided. In some embodiments, the display device can further include the array substrate as discussed above in relation to any one of the embodiments of the present disclosure. In the following, the display device will be descried in detail with reference to FIG. 6 and FIG. 7.

In particular, FIG. 6 illustrates a cross-sectional view of an exemplary display device 10 according to some embodiments of the present disclosure. As shown in FIG. 6, the display device 10 can include one or more array substrates as discussed above, wherein each display substrate can be arranged facing one another.

It will then be appreciated that the array substrates can be provided as the array substrate 100 as illustrated in FIG. 4, or, alternatively, the display substrate can be the display substrate 200 as illustrated in FIG. 5. As shown in FIG. 6 and FIG. 4, the array substrate 100 can include the display sub-pixels 111 provided over the base substrate 110, the display sub-pixels 111 wherein the substrate can also include a first insulating layer 121, the pixel electrodes 112, the second insulating layer 122 and the common electrodes, i.e. the first common electrodes 113 and the second common electrodes 114, arranged successively over the base substrate 110, and the first common electrodes 113 and the second common electrodes 114. In some such embodiments, the first common electrodes 113 can be insulated from the second common electrodes 114.

As shown in FIG. 6 and FIG. 5A, the display substrate 200 can also include the color film layer 200 and the lens layer arranged successively over the base substrate 210. The color filter portions 222 and the display sub-pixels 111 of the array substrate 100 can be arranged facing each other.

In some such embodiments, the surfaces of the color filter portions 222 on the opposing or exposed surface from the base substrate 210 can include concave portions, wherein the microlenses 230 can be placed or arranged within an inside surface of the concave portions of the color filter portions 222.

In some embodiments, the display device can be provided as a liquid crystal display device, wherein the liquid crystal display device can further include a liquid crystal layer, (not shown in figures), wherein the liquid crystal layer can be arranged or placed between the array substrate 100 and the display substrate 200.

Additionally, a backlight source can also be provided to the display device, (not shown in figures), wherein the backlight source can be placed or position about a side portion of the array substrate 100, this side portion being located about a surface array substrate 100 that is opposite the display substrate 200.

FIG. 7 is a schematic plan view and a display principle diagram of the display device 10 according to some embodiments of the present disclosure, the display device 10, for example, corresponds to the display device shown in FIG. 6. As shown in FIG. 7, the display device 10 includes first display regions 161 corresponding to the second common electrodes 114 and a second display regions 162 corresponding to the first common electrodes 113.

For example, the microlenses 230 are configured to separate the light 151 emitted by the first display regions and the light 152 emitted by the second display regions, so that a first image 155 and a second image 156 that are separated in space can be formed within the working distance range of the display device 10. For example, light 152 emitted by the first display regions is employed to form the image pixel of the first image 155, for example, the left eye image, light 153 emitted by the second display regions is employed to form the image pixel of the second image 156, i.e. the right eye image.

In some embodiments, the first common voltages received by the first common electrodes 113 and the second common voltages received by the second common electrodes 114 are different. In some embodiments, the strength of the light 152 emitted by the first display regions 161 and the strength of the light 153 emitted by the second display regions 162 can also be different.

By varying the voltages received by the first or second common electrodes and the corresponding strength of light images having varying properties can then ultimately be displayed between the right and left eye, which, as a result, allows for display of a first image 155 and a second image 156 wherein parallax exists between them.

In such a case, when a left eye and a right eye of a user respectively receive a first image 155 and a second image 156, the user can have stereoscopic perception, that is, the user can see a 3D image 157. Therefore, the display device 10 according to some embodiments of the present disclosure can realize 3D display function without reducing resolution.

In some embodiments, when the first common voltages received by the first common electrodes 113 and the second common voltages received by the second common electrodes 114 are the same. In such an instance, the strength of the light 152 emitted by the first display regions 161 and the strength of the light 153 emitted by the second display regions 162 would then be the same, as a result, the first image 155 and the second image 156 are essentially the same.

In this case, when a left eye and a right eye of a user respectively receive a first image 155 and a second image 156, the user can see a 2D image. In addition, the resolution of the display device 10 in FIG. 7 is M1×N1, wherein, M1 is the number of display pixels in the second direction D2, N1 is the number of display pixels in the first direction D1, that is, the display device 10 in FIG. 7 can realize 2D display function without reducing resolution.

In some embodiments, as shown in FIG. 7, the display device 10 includes the first display regions corresponding to the first common electrodes 113 and the second display regions corresponding to the second common electrodes 114. For example, the microlenses 230 are configured to separate the light 152 emitted by the first display regions and the light 153 emitted by the second display regions, so that the first image 155 and the second image 156 that are separated in space can be formed within working distance of the display device 10. For example, the light 152 emitted by the first display regions is employed to form the image pixel of the first image 155, i.e. the left eye image, the light 153 emitted by the second display regions is employed to form the image pixel of the second image 156, i.e. the right eye image.

In some embodiments, when the first common voltage received by a first common electrode 113 and the second common voltage received by a second common electrode 114 are different, the strength of the light 152 emitted by the first display regions 161 and the strength of the light 153 emitted by the second display regions 162 are different, as a result, parallax exists between the first image 155 and the second image 156; in this case, a left eye and a right eye of a user respectively receive the first image 155 and the second image 156, the user can have stereoscopic perception, that is, the user can see an image 157 that has 3D visual effect, therefore, the display device 10 provided by embodiments of the present disclosure can achieve 3D display function without reducing resolution.

In some embodiments, when the first common voltage received by a first common electrode 113 and the second common voltage received by a second common electrode 114 are the same, the strength of the light 152 emitted by the first display regions 161 and the strength of the light 153 emitted by the second display regions 162 are the same, as a result, the first image 155 and the second image 156 are essentially the same; in this case, a left eye and a right eye of a user respectively receive the first image 155 and the second image 156, the user can see a 2D image. In addition, the resolution of the display device 10 in FIG. 7 is equal to M1×N1, wherein, M1 is the number of display pixels in the second direction D2, N1 is the number of display pixels in the first direction D1, that is, the display device 10 in FIG. 7 can realize 2D display function without reducing resolution.

In some embodiments, the device as described herein can include common electrodes and pixel electrodes which are located in different layers so as to form an advanced super dimensional switch (ADS). In the ADS mode, a multi-dimensional electric field is formed with both an electric field generated at edges of slit electrodes in a same plane and an electric field generated between a slit electrode layer and a plate-like electrode layer, so that liquid crystal molecules at all orientations, which are located directly above the electrodes or between the slit electrodes in a liquid crystal cell, can be rotated, In this way, the work efficiency of liquid crystal can be enhanced and the light transmittance can be increased. The ADS mode can improve the image quality of the thin film transistor liquid crystal display and has advantages of high resolution, high transmittance, low power consumption, wide viewing angle, high aperture ratio, low chromatic aberration, high response speed, free of push Mura, etc.

As contemplated herein each pixel electrode within the array substrate can thus be provided having an ADS configuration of the liquid crystal display comprises two layers of transparent electrodes, i.e. a first transparent electrode and a second transparent electrode disposed above the first transparent electrode.

One of the first transparent electrode and the second transparent electrode can then be used as a pixel electrode and connected to a drain electrode of a thin film transistor, wherein the other can used as a common electrode and connected to a common electrode line.

The second transparent electrode can then include a stripe electrodes having a certain width and separated from each other at a certain interval, so the second transparent electrode is also called a slit or channel electrode. The second transparent electrode and the first transparent electrode can then be arranged with one overlapping the other, and the first transparent electrode and the second transparent electrode can then be separated from each other with an insulating layer.

In some such embodiments, the array substrate can include various gate lines, data lines, and pixel units defined by or between the gate lines, wherein the gate lines and data lines intersect one another.

Further, the pixel unit can also include a pixel electrode and a thin film transistor. The pixel electrode can then include strip electrodes, and an opening which is provided between adjacent strip electrodes. The thin film transistor in such instances can include a gate electrode, a source electrode, and drain electrodes. In some such embodiments, the strip electrodes of each pixel electrode can all incline in one direction.

When the conventional liquid crystal display operates, liquid crystal deflects as driven by the electric field, and the liquid crystals in each pixel unit can be configured such that they only have one deflection angle. Due to anisotropy of the liquid crystal, the liquid crystal display can then have differences in brightness when it is viewed from different viewing angles, and associated chromatic aberration.

In some additional embodiments, the pixel unit can have a two-domain display region, i.e. wherein the display region of the pixel unit is a region covered by the pixel electrode except for the thin film transistor. In other words, the stripe electrodes in each pixel unit can instead have two inclination angles. In this case, when the liquid crystal display operates, the liquid crystal deflects as driven by the electric field, and the liquid crystal in each pixel unit can then be provided having two deflection angles.

Due to the averaging effect of deflection of the liquid crystal, differences in brightness of the liquid crystal display when the liquid crystal display is viewed from different viewing angles decrease, and chromatic aberration is improved in some degree.

Further, it is also contemplated herein that the pixel electrode and common electrode can be located in a common layer so as to form a fringe field switching mechanism (FFS).

Also contemplated herein is an arrangement wherein the pixels have multiple domain structures. In other words, each pixel, or each adjacent pixel, can be provided having different domain structures corresponding to different common electrodes.
